Abstract

In both nursing practice and research settings, valid and accurate information on the cognitive function of elderly persons is necessary. However, methods and criteria for evaluating an elder's mental status are inconsistent. A formal screening tool such as the Mini Mental State Examination (MMSE) would enable nurse clinicians and researchers to use a common method for identifying cognitive impairment. In addition, the MMSE score can readily describe levels of impairment across settings. Although certain limitations exist when using this instrument, the MMSE has been successfully employed by some nurses in selected clinical and research settings as a brief but accurate screen of cognition in older persons.
